i also didnt get my email, i preorderd it in june 1st
and is it poible to use this emmc in the rock 5b: https://pine64.com/product/64gb-emmc-module/
i have it laying arround
It’s Golden Week now, so I wouldn’t expect anything to happen until at least the 8th, probably not until the 10th that everything is back up to speed. My guess is they tried to get a few out the door before heading off for vacation.

i didnt knew this because i am in italy
I see some models start shipping. When do you/how do you even get the redeem code? Also, seems to be constantly out of stock on allnet so is it only developer preorders that were available? I ordered a redeem code in february.
From current schedule, Feb and earlier coupon code will be all fulfilled in Oct for sure. So stay tuned.

My rock 5 is already on the way, so they are shipping their queue. They encouraged in e-mail to get additional cooling, but this one was sold out at the time of my order (and still not available). Is that 2 wire fan or pwn enabled 3 wire? anything standard will fit?

Yes, it will be ok, radxa eMMC have two connectors, but one of them is only for positioning and it’s not needed 
oh cool but i checked the pinout and a few pins are not quite the same
rock 5b:
rockpro64 (one of the sbc that offitialy supports this emmc):
i am not so sure that it will work because of the gnd pins of the rockpro64 on the emmc connector but if i look at the pine64 emmc the pinout matches the radxa connector, maybe to fit on the rock 5b i have to desolder the 15 pin haederand the voltages should be the same 3.3 and 1.8 volt, it seems to be that both are eMMC 5.1 memmory chips from sandisk (rockpro64 32GB and larger) and foresee (rockpro64 16GB and smaller and all rock 5b)
Pine64 16GB Foresee module is confirmed to work. And I doubt Pine64 changed pinout with the better / higher capacity modules.
it is even the same pcb. i think the emmc protocoll is just sdio also a standart and it never hurts to ask before destroying something. 
and its cool to see that the opensource world is from all sides compatible
eMMC has different procotol revisions and SDIO can use different bus widths as such even ODROID eMMC modules (Hardkernel invented this pseudo standard) are not compatible between all boards: https://wiki.odroid.com/accessory/emmc/reference_chart
But with a Pine64 64GB module there should be no issues.
thats verry cool, and for anyone interrested the 64GB pine64 emmc:
, and when will shipping start i preorderd it at june 1st
You prob need a very specific application to need eMMC on the rock5b as with such a great m.2 connector that can fit standard m.2 nvme onboard without the Rock4 extender, that is much faster and cheaper than eMMC.
Which also brings up another gripe and guess its just economies of sale but why is eMMC often more than double the price of similar size NVME?
I guess the double connector with one being electrically a dummy adds cost and board space, its the cost for capacity that always raises an eyebrow of ‘is it worth it?’ for me, but guess if you have the application its a cost you will meet.
Home-assistant or OpenHab (I have forgot which and the exact module name) do a zram/overlayfs module that loads the whole OS ephemeral that writes once on shutdown to keep persistence and can keep a budget micro sd running a long long time.
Then there are things like the RasPiKey https://thepihut.com/products/raspikey-plug-and-play-emmc-module-for-raspberry-pi and again not ‘cheap’, but I guess just functions as SD for all.
Maybe the specific ‘application’ could be ‘3W lower idle consumption’? Asides that he already owns the eMMC module…
Its a hard push as with current UK electricity prices it would take approx 3 years 24/7 to break even on the price increase.
i have the emmc module thats why i want to use it alongside the m.2 because i want it as second drive maybe for anothe linux distro or just to store some files
Yeah its just my pet gripe that they don’t offer a awful lot of value and apart from onboard don’t use, but have purchased a few in the past.
I am interested what Radxa may do with a possible Rock5A cut down RK3588S and even if eMMC should be a thing.
I think I am prob stereotypical in use as if its onboard already then use, but tend to not do with a variety of other storage of micro sd, nvme, sata and usb…
I mean, if you are using it as an actual embedded board for industrialish reasons, rather than using it as a desktop computer, the m.2 often gets used to replace whatever you’d do with mpci (which is a mess and only really used for wifi cards as a result).
For example, i use m.2 based pcie relay cards, like from ACCES I/O.
I could get boards and drive them over i2c/spi for sure, but m.2 is actually more consistently implemented from board to board and platform to platform (IE i don’t have to hook a logic analyzer up and figure out what is going wrong with SPI/I2C in this vendor’s drivers, or which 73 pins they are shared with but aren’t listed properly.). Whether it’s “we put 1mhz in a device tree/ACPI entry instead of 10mhz or whatever”, m.2 tends to be more consistent.
I agree in the “desktopish” setting, 99% of users seem like they would use it for storage cards.
The RK3588/RK3588S block layout bears this out - the you can’t use sata at the same time as m.2’s pcie IIRC (or at least, on the available 3588S boards you can’t)
